Filter by:Cigarette smoking is the leading preventable cause of death in the U.S. Nearly 4 million U.S. smokers are hospitalized each year, many of them at high risk for tobacco-related disease or death. A hospital admission provides an opportunity for a smoker to quit. Smoking cessation counseling provided in the hospital is effective, but only if it continues for >1 month after discharge. Smoking cessation medications add benefit to counseling but are not often used. The challenge is to translate this efficacy research into routine clinical practice. The major barrier is to make the transition from inpatient to outpatient care. An evidence-based, cost-effective intervention model that can be adopted by U.S. hospitals is needed to realize the potential impact of hospital smoking interventions. The Specific Aim of this project is to conduct a randomized controlled comparative effectiveness trial of two strategies to promote smoking cessation in hospitalized patients: (1) a hospital-only intervention that meets the current standard of the National Hospital Quality Measures("Standard Care"), and (2) an "Extended Care Management" model with 2 components that aims to encourage and facilitate the sustained use of smoking cessation treatment (counseling and medication use) after discharge in order to achieve long-term abstinence. It adds to Standard Care 3 months of telephone-based contact after discharge and feature 2 innovations: (1) to increase medication use, smokers willing to make a quit attempt receive a free, refillable 30-day sample of their choice of FDA-approved smoking cessation medication at hospital discharge; (2) to increase counseling cost-effectiveness, interactive voice recognition (IVR) technology is used to make automated telephone calls to identify the smokers interested in or most likely to benefit from continued counseling after discharge. The trial will enroll 330 adult smokers admitted to Massachusetts General Hospital, a 900-bed teaching hospital. Outcomes will be measured 1,3 and 6 months after hospital discharge. Study hypotheses are that the enhanced care arm, compared to usual care, is feasible and will increase (1) the use of smoking cessation treatment after discharge, (2) the duration of post-discharge tobacco abstinence, and (3) validated tobacco abstinence 6 months after hospital discharge (primary outcome). The principal secondary outcome measure is self-reported 7-day point prevalence tobacco abstinence after hospital discharge. Other secondary endpoints include self-reported point prevalence abstinence at 1 and 3 months, prolonged abstinence (self-reported tobacco abstinence at 1, 3, and 6 months). The cost-effectiveness (cost per quit) of the interventions will be also be compared.
The purpose of this study is to assess the effects of mindfulness training (MT) compared to standard Smoking Cessation Therapy (SCT) on smoking cessation and stress provocation in individuals trying to quit smoking.
The primary objective of this research is to explore relations between impulsive behavior and smoking-cessation success among treatment-seeking teens enrolled in a quit-smoking program. It is hypothesized that teens who do not successfully stop smoking (or who drop out of the treatment program) will be more impulsive (from measures taken just prior to treatment) than those who do successfully stop or significantly reduce rate of smoking.
The purpose of this study is to determine the extent to which an Intentional Behavioral Intervention will increase tobacco quit rates post release among incarcerated men and women.
We are currently working in 16 middle schools across Los Angeles, Santa Monica and Torrance to test out a voluntary after school program called Project CHOICE, which focuses on helping students decrease their alcohol and drug use. We are conducting surveys in all schools over three years and providing the intervention in 8 schools in the 2008-2009 school year and in the other 8 schools in the 2011-2012 school year. This is a program we have provided before in middle schools and we found that it was effective in curbing alcohol and drug use among students who voluntarily attended and among all students at the intervention school.
The investigators' general hypothesis is that African-Americans (AAs) smoke more for positive reinforcement from nicotine with a "peak-seeking" pattern of smoking (smoking individual cigarettes more intensively with greater intake of nicotine and tobacco smoke toxins), while whites smoke more for negative reinforcement with a "trough-maintaining" pattern (avoiding withdrawal by maintaining more consistent nicotine levels throughout the day by means of a more regular smoking pattern). We, the investigators, believe that these patterns are linked to identifiable racial differences in nicotine pharmacology. For this study we hypothesize that if AAs behave more like nicotine "peak-seeker" while whites behave more like nicotine "trough-maintainers", that AAs will respond to switching from regular to low nicotine yield commercial cigarettes by smoking each cigarette relatively more intensively with a relatively smaller increase in daily cigarette consumption (cigarettes per day or CPD) as compared to whites.
The primary objective of this research is to evaluate the effectiveness of this type of smoking cessation program by comparing a treatment group with a control group. A secondary objective of this research is to explore relations between impulsive behavior and smoking-cessation success among treatment-seeking teens participating in a quit-smoking program. Hypothesis 1. A greater proportion of the participants in the treatment condition will be verified as abstinent from smoking during the course of treatment than participants of the control condition. Hypothesis 2. It is hypothesized that teens who do not successfully stop smoking (or who drop out of the treatment program) will be more impulsive (from measures taken just prior to treatment) than those who do successfully stop or significantly reduce rate of smoking.
The major aim of this study is to test the effectiveness of a bundled, multi-level intervention (Sister to Sister) on smoking cessation outcomes in female smokers residing in public housing neighborhoods. Hypothesis 1.1: As compared to the control group, women receiving the Sister to Sister Intervention will have higher 7-day point prevalence quit rates at 6- and 12-months as validated by salivary cotinine. Hypothesis 1.2: As compared to the control group, women receiving the Sister to Sister Intervention will have higher 6- and 12-month prolonged smoking abstinence as validated by salivary cotinine.
Despite the significant health, social and economic costs of cigarette smoking, 17% of Ontarians still currently smoke. Use of smoking cessation pharmacotherapy such as Zyban (bupropion HCl) has been shown to double quit rates but such medications are under-utilized by smokers attempting to quit. It has been suggested that the high price of pharmacotherapy may act as a barrier to accessing such treatment.The main objective of this study is to evaluate the methods and effectiveness of providing smokers who want to quit with 8 weeks of free Zyban in combination with smoking cessation counselling through family health teams and community health centres across the province. Hypothesis: Ontario smokers who receive 8-weeks of free bupropion in combination with brief counselling will have higher smoking cessation rates than the standard population cessation rates.
To test whether naltrexone compared to placebo can reduce heavy drinking and improve smoking cessation outcomes in heavy drinkers seeking smoking cessation treatment.
